Nutraplanet PLCAR Dosing

Just got my order in. On the bottle it says "Take up to 500mg approximately 30 minutes before athletic activity or before bed.". However In the write up it say to take 2 grams per day. I've also read others post to take 1 gram in the morning and 1 gram in the pm. Should this be taken on an empty stomach or with food or does it matter?. I'd like to take a dose now just to see how I feel....

Thanks guys. By the nice job on the labels Nutaplanet!. Last time I purchased a bulk powder from you guys it just had a plain white label with the name of the product. No dosing information at all. The other question I have though is, why the inconsistency of dosing information on the bottle to dosing information in the write up?. Why not keep everything the same?.

TBH, I am not 100% sure. Could be a printing error. However, the 2g per day seems to be the going rate. I will be getting the Ultima/PLCAR stack (should be pre w/o awesomness) and will be going at 2g per as well
